the 'utmost strength nml rigidity. l

A still further object ol the invention is' to provide o truck tllot'is c'specinlly dnptefl for us in connootion with benmless broke mecl1- onism and is of suoli nature ond constmction :is to permit the use oi the ordinary broke mechanism where desired.

` A still fui-thor object of the, invention is to provide a, truck with means for supporting the broke carrying: lovers of o. laoninilos brake system, nucl further to so arrang thel broke lavora und rods ns to soc-ure unifonn notion of all of tho lrmlivs,
